Just about the same size, or exactly the same size? OEM is a looser fit because of the gasket/bushing, aftermarket to aftermarket should be a very tight, but doable fit.

Rubber mallet, cold on the header and heat on the canister.

maddog,

I read you have the same pipe as i do on one of your bikes. My pipe came with two little rings about an inch and a quarter in diameter. Do these go between the header pipe and the engine block?

Those are your exhaust gaskets, and yes they go between the header and where it bolts onto the head.

Take a blow torch and heat the canister where they should meet. Have someone take the header and someone take the canister and shove them together. You could also bolt on the headers, then heat the canister side and use the bike to hold the header. Keep heating until you can put the bolts in to mount the canister to the bike. Bang it with a rubber mallet if it doesn't seem to want to go. Heat and a mallet should work.

got it all working now, had to get the end cut off the pipe and new pipe welded on works great.

Hmm, we've had a couple of slip ons (e-series and t-4) slide right onto the powerbomb.

Sorry to hear you had such trouble, but good to know it's working now.
